Hi
Usually Some PCB With Tegra Need Remove Some Resistor or Short Some Resistor For Enable JTAG Access...So Maybe This is Needed For Detect Chip For Read/Write
But I'm Not Sure...

Did You Connect Both VCC/VCCQ..? Because I did but I have high value Like 0.90MA.it's not correct,...

This short two points mean hard lock reset to prevent MCU from entering to boot stage while USB connected. Because without usb we has to much consuption on VCC and VCCQ.
